Public bug reported: [Impact] System stuck at boot when Intel 7560 is in use, because devlink is waiting for reference to be released.
[Fix] Commit "devlink: remove the registration guarantee of references" weakens the refcount requirement for devlink {,un}registering, [Test] System reboots over 2000 times when the fix is applied. [Where problems could occur] devlink is part of net core API, so it has many users, therefore all of devlink users can be affected by this fix. However, all the devlink users can be affected by the same issue (i.e. waiting for reference to decrease to 0), hence this is still a desirable fix. ** Affects: linux-oem-6.1 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux-oem-6.1 (Ubuntu Jammy) Importance: Medium Status: Confirmed ** Also affects: linux-oem-6.1 (Ubuntu Jammy) Importance: Undecided Status: New ** Changed in: linux-oem-6.1 (Ubuntu Jammy) Status: New => Confirmed ** Changed in: linux-oem-6.1 (Ubuntu Jammy) Importance: Undecided => Medium ** Changed in: linux-oem-6.1 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-6.1 in Ubuntu. https://bugs.launchpad.net/bugs/2036515 Title: Fix system boot hang caused by devlink Status in linux-oem-6.1 package in Ubuntu: Invalid Status in linux-oem-6.1 source package in Jammy: Confirmed Bug description: [Impact] System stuck at boot when Intel 7560 is in use, because devlink is waiting for reference to be released.
